The world of payments is moving fast, and one of the newest innovations reshaping how merchants accept transactions is Tap on Phone. In Xplor Pay’s latest webinar, our team explored what Tap on Phone is, why it matters, and how SaaS platforms can offer it through their mobile app to deliver more value to their merchants. 

This discussion was designed to educate software leaders about the opportunities and practical considerations of turning mobile devices into payment terminals. Tailored for SaaS founders, product and engineering leaders, and payments teams looking to integrate modern mobile payment acceptance into their SaaS mobile application. 

What is Tap on Phone? 

When it comes to payments, terminology can get confusing. You may have heard phrases like “tap to pay” or “softPOS” thrown around, but in this webinar, we focused specifically on Tap on Phone. 

So, what does it mean? Simply put, Tap on Phone allows merchants to use an NFC-enabled iPhone, Android phone, or certain Android tablets as the payment terminal itself. That means no extra card readers or hardware are needed—just the mobile device. 

With Tap on Phone, customers can make payments by tapping any of the following directly on their smartphone: 

  • A contactless card 
  • A digital wallet 
  • Or even a wearable device like a smartwatch 

This turns the merchant’s everyday device into a fully functional payment acceptance tool, creating a faster, more modern checkout experience. 

Where Tap on Phone Fits Best 

While Tap on Phone has broad potential, certain industries are especially well-positioned to benefit from it early on. These are businesses where mobility, convenience, and speed are critical to both employees and customers: 

  • Field Service & Trades: Think HVAC technicians, plumbers, or electricians. These professionals often need to collect payments onsite—sometimes for one-time jobs, sometimes to set up recurring billing. Tap on Phone eliminates the need for extra devices and allows them to capture payments instantly. 
  • Healthcare & Professional Services: In dental offices, medical clinics, or other “pay at the chair” environments, Tap on Phone removes the friction of passing around terminals or waiting for invoices. Staff can simply accept payment on the same device they use to manage appointments or records. 
  • Delivery & Transportation: From couriers to logistics companies, Tap on Phone makes it possible to close out transactions at the doorstep or on the move, improving the customer experience and cash flow. 

In short, any industry that requires employees to move beyond a fixed counter or office is a natural fit for this technology. It gives them the flexibility to collect payments anywhere, without relying on additional hardware. 

Why Tap on Phone Matters Now 

The timing for Tap on Phone couldn’t be better. Two major market shifts have paved the way for rapid adoption: 

  1. EMV and Contactless Normalization 
    Over the past decade, consumers have moved from swiping cards to inserting chips, and now, tapping. Contactless has become second nature at grocery stores, gas stations, and retail checkouts. The “tap” motion no longer feels new or unfamiliar, —it’s expected. 
  1. Wallet-First Consumers 
    The rise of Apple Pay, Google Pay, and digital wallets has accelerated since COVID-19, making phones and wearables a primary payment tool for millions. Many consumers now leave home confident they can pay with just their phone or smartwatch. 

Together, these two waves mean the barriers to Tap on Phone adoption are already low. Consumers are comfortable tapping, merchants are eager to reduce hardware dependencies, and SaaS platforms have an opportunity to differentiate their offerings with a sleek, mobile-first payment option. 

6 Key Considerations for SaaS Platforms 

For software providers, Tap on Phone isn’t just a shiny new feature—it comes with practical questions that impact adoption, pricing, integration, and ultimately revenue. During the webinar, we unpacked some of the “quiet concerns” we hear most often from SaaS leaders and what our research shows in response. 

1. Adoption & Devices 

A common worry is whether merchants will be comfortable having employees accept payments on personal or company-issued devices. Research suggests adoption barriers are lower than expected. Most employees already rely on smartphones for business tasks, and merchants value the simplicity of enabling payments without shipping extra hardware. Notably, iOS has emerged as the dominant platform for Tap on Phone adoption. 

2. Pricing & Total Cost 

Tap on Phone transactions are classified as card-present (CP) rather than card-not-present (CNP), which typically means lower interchange fees. While providers may charge small technology fees for access to device security, these are often offset by eliminating hardware costs. The net impact depends on the pricing model (flat-rate vs. interchange-plus), but many SaaS providers will find overall costs trending downward. 

3. Integration Impact 

The big question: will this add integration complexity? For most SaaS platforms, the answer is no. With a well-built mobile SDK, Tap on Phone can usually be integrated in a matter of weeks, not months. At Xplor Pay, we even use our own mobile SDK in our merchant-facing app—meaning it’s tested, proven, and ready for partners to leverage. 

4. Security & Complexity 

Some assume mobile-based payments introduce risk, but in reality, Tap on Phone relies on industry-leading device security standards (like PCI compliance certifications). No card data is stored locally, and leveraging existing device security makes the process both safe and simple. For SaaS teams, it can actually reduce complexity compared to managing fleets of terminals. 

5. Payment Experience & UX 

Merchants want to deliver a smooth checkout, and Tap on Phone enables exactly that. Faster transactions, modern workflows, and easier processes for employees translate into happier staff and better customer experiences. For SaaS providers, this is a key differentiator that adds real value to the platform. 

6. Revenue Implications 

At the end of the day, it comes down to revenue. Tap on Phone is a marketable feature that gives SaaS platforms a compelling way to increase payment attach rates, reduce accounts receivable delays, and drive faster cash flow for merchants. It supports growth on both the new bookings side (winning new customers) and the back-book side (expanding adoption among existing customers). 

Practical Applications of Tap on Phone 

To see the impact of Tap on Phone in action, it helps to look at how different types of businesses can use it in their day-to-day workflows: 

  • Recurring Field Service 
    For industries like lawn care or cleaning services, the challenge is often capturing a card on file for ongoing billing. With Tap on Phone, technicians can capture payment details with a simple tap during the first visit, then automate future invoices without chasing down customers each time. 
  • One-Off or High-Ticket Jobs 
    Think of HVAC repairs or installations. Traditionally, these can involve delays in collecting payment—waiting for invoices or mailing checks. With Tap on Phone, the technician can present the invoice right on their mobile device and accept payment immediately, improving cash flow and reducing accounts receivable. 
  • Retail-Lite or Mobile Storefronts 
    For merchants running pop-up shops, market stalls, or small brick-and-mortar stores that rely on tablets or phones, Tap on Phone reduces the need for extra terminals. Over time, it can help streamline operations by consolidating software and payments into one device. 

In all of these cases, the outcome is the same: less hardware, faster payments, and a modern customer experience that keeps businesses moving forward. 

Benefits at a Glance 

Tap on Phone brings clear advantages for both merchants and the SaaS platforms that serve them. Here are the key benefits summarized: 

  • No extra hardware — eliminate the need to ship, track, and support card readers or terminals. 
  • Faster activation — merchants can start accepting payments immediately with just an API key and their mobile device. 
  • Lower costs — fewer hardware expenses and the potential for lower interchange fees through card-present transactions. 
  • Higher app usage — by embedding Tap on Phone in your mobile app, you give merchants another reason to adopt and engage with your software. 
  • Modern user experience — fast, contactless payments that meet customer expectations and differentiate your platform from competitors. 

These benefits combine to make Tap on Phone not just a convenience, but a strategic tool for SaaS companies looking to strengthen customer relationships and grow revenue.
